Lokalisering av vågkraftanläggningar : Metodutveckling med GIS och fallstudie Bohuskusten

In this thesis work a Geographical Information System (GIS) based methodology to identify locations suitable for the installation of wave energy converters has been developed. Parameters of importance have been identified and a GIS-database has been set up, containing data about the marine environment. In a case study of the Swedish west coast the methodology has been applied, resulting in a number of maps showing possible areas. The results show that large areas are suitable for installation of wave energy converters, from a technical and economical point of view. When consideration is taken to other interests in the area, such as navigation, fishing and environmental protection, the size of the suitable area diminishes considerably.

Relationship between moose (Alces alces) home range size and crossing wildlife fences

Wildlife fences are today commonly used along highways to reduce the risk of vehicle collisions with wildlife. Since traffic and roads have expanded over the years, wildlife behaviour has become more interesting not only for the prevention of vehicle collisions but also to understand how human activities impact their natural habitats. Moose is one of those animals that have increased in interest in such studies. In this study, I tested if the probability to cross wildlife fences of moose would increase with increasing home range sizes, and also at what time of the year they cross. The study area is situated in Nordmaling municipality, located in Northern Sweden in the County of Västerbotten.

Har antalet naturvärdesträd i Sverige förändrats mellan 1999-2009?

Forestry and forest products are vital components of the Swedish economy but the forest is also important for recreation, hunting, out-door life and conserving biodiversity. The Swedish Forest Act has two equally important objectives, production and environmental protection. Polytax is the Swedish Forest Agency´s inventory programme which monitors progress toward the two objectives in connection with regeneration fellings. It includes data on environmental protection measures taken in connection with regeneration fellings. 30 § of the Swedish Forestry Act and related regulations specify the demands for conserva-tion of nature.

Bredspridning av grönmassa :

There are a great possibility to shorten the time between mowing and preservation by spreading of ley crops in connection to the conditioning. In this case the cellular respiration (the plants breeding that consume sugar until the crop is ensiled) should not continue as long and the forage will perhaps get a higher nutritional value. The capacity of the next machine could also be higher because the rake gives swaths with a lot of material. There is also a possibility that spreading of ley crops gives the material a more homogeneous content of dry matter and that gives a reduced growth of clostridium. This is particularly important when the method of harvest doesn?t include any mixing of the material like it does with a round baler or silagewagon.

Smartphones, tablets and more recently, cameras is examples of mobile units.

Phosphorus in agricultural soils around the Baltic Sea : comparisons of different laboratory methods as indices for phosphorus leaching to waters

Eutrophication of the Baltic Sea is a serious problem. A major contributing factor is diffuse losses of phosphorus (P) from agricultural land in surrounding countries. In order to estimate P losses, environmental monitoring of small agriculture-dominated catchments is being carried out in most of these countries. Evaluation of the risk of P leaching to waters is usually based on chemical tests originally developed to quantify the amount of soil P available for plant production. The tests are performed in different ways in the different countries and a number of different extraction agents are in use.

Är Leviathan giftig? : Autonomi och repression som förklaringar till regimskillnader i förväntad livslängd

During the last decade a number of studies have been published that investigate how the most fundamental aspect of political organization, the regime type, affects population health. The results unanimously show that citizens of democracies live longer and healthier lives than citizens of non-democracies. Many explanations for this have been suggested, among these are that democracies redistribute more and invest more in salutogenic resources, and that the tendency of dictatorships to control the media negatively affects the ability to spread information crucial to public health. When these mechanisms are controlled for, however, it turns out that democracy has a large residual correlation with for example life expectancy, which suggests that other mechanisms are also involved.In this paper two new mechanisms regarding the possible psychosocially mediated health effects of the regime type are investigated, namely political repression, and the possible negative effects this might have on the levels of chronic stress, and autonomy, which connects to a large previous literature in social epidemiology. In the paper an ecological cross-country design is used and country-level data, provided mainly by the World Bank and Freedom House, is analyzed with a simple multiple OLS-regression model.

Cypern-målet : Upplägget, lagstiftningen och konsekvenser

The financial result of a transfer of ownership or external sale is to a great extent depend-ent on how the transfer is implemented and how the tax rules apply. The applicability of the Swedish tax rules regarding transfer of ownership in closely held companies largely de-pends on the interpretation of the prerequisite, equal or similar activity, which can be found in section 57, clause 4 of the Swedish Income Tax Act.The ruling made by the Supreme Administrative Court in RÅ 2010 ref. 11 changed the concept of equal or similar activity. The ruling lead to that the shares in a closely held com-pany was qualified due to that the capital from the original company had been transferred to the operating company. According to the ruling the original company had been split into several companies, thus was the companies considered to carry out equal or similar activity.

Tjustempiren : fallstudier av Casimirsborg och Blekhem

This paper concerning the regional architectural term known as the Tjust Empire style analyses manor houses built in the Tjust area by the east coast of Småland in the period 1810-1860. The term Tjust Empire style was invented in 1937 by PhD. Manne Hofrén in his dissertation on architecture in Kalmar län in the period 1650-1850. The aim of the paper is firstly to determine whether there is a distinct difference between the regional Tjust Empire style in architecture and the common Swedish empire style or as its Swedish equivalent is known; the Karl Johan style. Secondly, the paper strives to analyse why and how the Empire style became so popular in the area during this period, focusing on architecture as a means to express social identity and status.

Torrfoder till katt : påverkan och konsekvenser

The cat has evolutionary become an obligate carnivore. Today it is common to feed the cat a dry food. Studies have shown that the dry formula can have negative consequences for the cat. A literature study where conducted to investigate whether the cats origin makes it incapable to compensate for the changes a dry food entails. The impact and implications regarding water intake, energy intake and blood glucose concentration when feeding the cat dry food where examined.

Yttrandefrihet i sociala medier

AbstractSweden has had a long tradition of freedom of the press and freedom of speech. Today the judicial area is regulated by the constitution of the press and the constitution of speech. The purpose of the two constitutions is to secure the right for every Swedish citizen to express their thoughts, opinions and feelings.The constitutions are designed to regulate the techniques with which the information is distributed and not to regulate the information in itself. This fact has caused a debate to arise on the subject whether the constitutions are still suitable to regulate the judicial area when the technical development causes the constitutions to get out of date and in need of constant updating. As a rule the usage of social media is not regulated by the constitution of speech the information distributed through these webpages can be included by the protection given by the constitution but very few of these webpages fulfill the criteria?s demanded by the constitution.The purpose of this essay is to ask the question whether the constitution of speech should be reformed to better regulate the technical development in the future.

Hur påverkar gummigolv i grisningsboxen suggans liggtider, liggbeteende och hennes tid för att lägga sig?

In the farrowing pens the amount of bedding material and the quality of the concrete floor has a huge impact on both the sow and the piglets. In this study imbedding of rubber flooring on the solid area in the farrowing pen was used to see if it had any effects on the sows lying behaviour when compared to concrete. Another important aspect was to evaluate if the rubber floorings had a high enough durability to resist the normal wear in a farrowing pen. Concrete flooring is assumed to have a higher thermally conductive effect then rubber which can affect the sow?s chance to cool down.

Jämförelse mellan våtkompostering och andra VA-system i omvandlingsområden : en fallstudie i Norrtälje kommun.

Eutrophication of the Baltic Sea and Swedish lakes remains a major problem despite many years of effort to reduce the emissions of nutrients. One major source is waste water systems, especially private sewage systems. These sewages accounts for a very large share of nutrients per capita in comparison with citizens connected to larger sewage treatment plants. Norrtälje community has the greatest number of private sewage systems in Sweden. Discharges of nutrients, especially phosphorus, to the Baltic Sea from these sewage systems are significant.

Analys av energianvändningen i kvarteren Carolina och Jenny : en fallstudie

An energy study has been performed on two blocks in an area called Gävle Strand. The buildings are owned by a tenant-owner?s association called brf Carolina and were built by the company Skanska 2008. The builder as well as brf Carolina are pussled by the fact that electricity use is higher than expected while heating is less. Skanska is also very interested in finding out how much heat recovery from stale exhaust air through a geo-thermal heat pump is contributing to the general heating requirement and energy balance in four out of the ten buildings located on the properties.To find possible answers to the higher electricity use a literature survey on user behaviour was conducted.

Naturvårdsavsättningar vid avverkning på Orsa Besparingsskog

Orsa Besparingsskog has an aim to take nature considerations in relation to the harvested volume and area of the annual felling. Around 15 percent of the acreage and 10 percent of the volume should be set aside. It is important to keep close to those figures to avoid future negative effects on the long-term harvesting planning. The purpose of this study was to use laser scanning data to estimate those proportions. The result showed that the proportion of conservation considerations in the ten selected objects in the study was significantly higher than the target of 15 percent of the acreage and 10 percent of the volume. The result showed a setting aside of 19 percent of the acreage and 17 percent of the volume.
